* tools: add support for model-specific tool registration
This PR goes with https://github.com/microsoft/vscode/pull/287666
This allows the registration of tools that are scoped to specific
language models. These tools can be registered at runtime with
definitions derived from e.g. the server.
I think we should adopt this and go away from the current
`alternativeDefinitions` pattern which we have used previously.
Example of having tools specific for GPT 4.1 vs 4o:
```ts
ToolRegistry.registerModelSpecificTool(
{
name: 'gpt41_get_time',
inputSchema: {},
description: 'Get the current date and time (4.1)',
displayName: 'Get Time (GPT 4.1)',
toolReferenceName: 'get_time',
source: undefined,
tags: [],
models: [{ id: 'gpt-4.1' }],
},
class implements ICopilotTool<unknown> {
invoke() {
return new vscode.LanguageModelToolResult([new vscode.LanguageModelTextPart('Current year is 2041 (GPT 4.1)')]);
}
}
);
ToolRegistry.registerModelSpecificTool(
{
name: 'gpt4o_get_time',
inputSchema: {},
description: 'Get the current date and time (4o)',
displayName: 'Get Time (GPT 4o)',
toolReferenceName: 'get_time',
source: undefined,
tags: [],
models: [{ id: 'gpt-4o' }],
},
class implements ICopilotTool<unknown> {
invoke() {
return new vscode.LanguageModelToolResult([new vscode.LanguageModelTextPart('Current year is 2040 (GPT 4o)')]);
}
}
);
```
